FACIAL HEAT APPLICAT'OR.

Application filed May 13,

Thisinvention relates to certain new and useful "improvements in facial heat applicators and has for its primary object to provide a heating device for the treatment of the skin of the'face of a person and is es-' pecially designed either for home use or for use in such establishments known as beauty parlors where a specialty is made of facial treatment.

A further object of the, invention is to provide a facial heating device in the form of an implement embodying a metallic head that is adapted to be electrically heated and with which a moistened pad or towel is associated for the generation of steam for use in treating the skin of the face and insures a constant and even application of heat as contrasted with the ordinary method of applying hot towels or the like. t

A still further object of the invention is to provide a device of the type above set forth in the form of a comparatively'small implement that may be readily handled and he'- also used for the treatment of certain ailments, such as toothache, earache etc, and where it is desirous to specifically apply heat at a particular point.

,Vith the above and other objects in View that will become. apparent as the nature of the invention is-better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

Inthe drawing, wherein like reference characters designate corresponding parts throughout the several views,

Fig. 1 is a rear elevational view of the heating device constructed in accordance with the present invention, socket plug having its cord through the handle of the device,

Fig. 2 is a side elevational view of the device,

F 3 is a side elevational view with a pad to be heated and partially broken awa in position upon the heating head of the device and so retained by a spring ring,

portion of the handle showing the heating element confined within'the-head,

Fig. 5 is a cross sectional view taken on line 5-5 Fig. 4 showing one of the resistant heating elements in plan view, and

Fig. 6 is a diagrammatic view of the electric wiring for the heat resistance elements.

Referring more in detail to the accompanying drawings, and particularly F i s. 1, 2 and 3, there is illustrated an electric eating device for facial treatment including a tubular handle 1 provided at its outer end with a heating head 2 that contains a plurality of electric heat resistance elements asso ciated with a. source of electric energy through the medium of the cord 3 passing through the tubular handle 1 and with an ordinary lamp socket plug 4 upon its other end.

municating with the interior of the hollow heating head 2 by means of the passage or central opening 8 in the rear wall 7. The electric cord 3 passing through the hollow handle 1 leads through the opening 8 for association with the heat resistance elements within the hollowhead. r

The heating head 2 is of truncated cone formation and includes an outer flat wall or face 9 of disk shape with an inclined side wall 10 constructed to form an angular groove 11 in the side wall and with a ring flange 12 at its extreme inner end that is internally threaded for enga ement with the threaded peripheral edge 0 the rear wall 7;

of the head, this construction being clearly shown in Fig. 4. The head 2 is of hollow formation as illustrated for housing the heat resistance elements with the inner annular y wall thereof provided with a shoulder 13 intermediate the front and rear sides of the As shown in Fig. 6, the'electric wiring for ance coils 16 being supported upon the mica sheets 19 that are substantially rectangular in plan view and spaced from each other as shown in Fig. 4 with the several resistance elements 16 positioned within the angular chamber 14 in the hollow head. The opposite ends of themica plates 19 are spaced 15 from the wall of the chamber 14 by the inclosing copper band intended'for the con duction of heat to the metal head 2. The frictional engagement between the opposite ends of the mica plates 19 and the copper 20 hand 20 operates to hold the resistance elements in spaced relation as shown in Fig. 4.

To cause the heat radiating from the resistance elements 16 to be absorbed by the forward wall 9 of the head, the chamber 15 in the head receives a plurality of asbestos discs 21 of a diameter less than said chamber and to be surrounded by an asbestos =ring 22 while mica rings 23 inclose the asbestos ring 22 and mica discs 24 space the ashestos discs 21 from the rear wall 7 of the head. As shown in Fig. 4, the wire terminals 18 extend to the lamp cord 3. It will therefore be seen that the heat is concentrated within the hollow head 2 and radiated directly to the outer fiat wall 9.

It. is intended that an absorbent pad or towel be placed in overlying relations with respect to heating head, and as shown in Fig. 3, a gauze sheet or covering 25 incloses a wad 26 of absorbent material, the sheet 25 inclosin the side wall 10 of the head and being retained in position by the coiled spring ring 27 that is retained by resiliency thereof in the annular groove 11. In lieu of the pad shown in Fig. 3, a portion of a towel orthe like may be placed in inclosing relations with respect to the head 2 and when moistened to the desirous degree, the moisture therein is converted into steam when the head 2 is heated for effective treatments of the face, such .as a massage or the like. WVith a device of this character, the heat remainsconstant and renders the heater more eflicient in use. The device is also service 55 able in the treatment of atoothache or earache or the like where the application .of

heat to a particular point is des1red.

Vhile there is herein shown and described the preferred embodiment of the presentinvention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is l..An electrical hand instrument f0 plying heat to portions of the face and the like, including a relatively thick hollow disk-like head having a rigid front wall to be heated, an electrical resistance element disposed in said head at the inner side of. said front wall, said head having an open rear end provided with a removable rear closure wall, a heat insulation in the head between the resistance element and said re- 1 movable rear wall, feed wires for the resist ance,element leading through said rear wall, and a laterally extendinghandle attached to said removable rear wall of the head.

. 2. An electrical hand instrumentfor applying heat to portions of the face and the like, including'a relatively thick hollow disklike head having a rigid front wall to be 5 heated, an electrical resistance element disposed in said head at the inner side of said ly extendinghollow handle havin one end fixed to a side of said block, said eed wires extending through said block and said handle.

3. An electrical hand instrument for applying heat to portions of the face and the like, including a hollow disk-like head composed of separable front and rear sections, an electrical resistance element disposed in said head at the inner side of the front wall of the latter, a heat insulation in the head between the rear wall of the latter and the resistance element, feed wires for the resistance element leading through the rear wall of the head, and a laterally extending handle attached to said rear head section.

4'. An electrical hand instrument for applying heat to portions of the face and the like including a relatively thick hollowv disk-like head having'a front wall to be heated, an electrical resistance element disposed in said head at the inner side of said front wall, a heat insulation in the head between the rear wall of the latter and the resistance element, feed wires for the resistance element leading through the rear wall of the head, and a handle attached to said rear wall, said head being tapered smaller from front to rear and having an annular peripheral securing band receiving groove near itsrear side to facilitate attachmentof a fabric covering thereto.

5. An electrical hand instrument for applying heat to portions of the face and the like. including a relatively thick hollow disk-- like head having a rigid front wall to be heated, a fiat electrical resistance element disposed in said head parallel with and at the inner side of said front wall, a relatively tion thereof, feed wires for the resistance thick heat insulation in the-head between the element leading through the handle and the rear wall of the latter and the resistance elerear wall of the head, and a fabric covering 10 ment, said rear Wall of the head embodying havin its margin secured about the peripha disk removably threaded into the body of ery of the head.
